Abstract: The calculation mathematical model of the dynamic performance and the energy consumption economy of battery electric vehicle was established. Total mass, mechanical efficiency of transmission system, rolling resistance coefficient and air resistance factor of battery electric vehicles have different effects on the dynamic performance and energy consumption economy, the calculation method of parameter sensitivity of their influence extent was proposed according to the model. The parameter sensitivity analysis of the dynamic performance and the energy consumption economy was also conducted on a battery electric vehicle. The results show that the value of transmission efficiency has a greater influence on the maximum speed, acceleration time and energy consumption. The conclusions provide a basis for the parameter design and optimization of the dynamic system, as well as the improvement of the dynamic performance and the energy consumption economy of battery electric vehicle.
